ASTM A178 Grade A Welded Steel Tube ERW Carbon-Manganese Steel Tube For Boiler And Superheater 0

ASTM A178 Grade A, Grade C, Grade D Welded Steel Tube ERW Carbon-Manganese Steel Tube for Boiler and Superheater

Material

ASTM A178 is a specification for electric-resistance-welded (ERW) carbon-manganese steel tubes. These tubes are primarily used in the manufacturing of boiler and superheater components. The material is designed to withstand high temperatures and pressures, making it suitable for various industrial applications.

Specification

The ASTM A178 specification covers two grades of welded steel tubes: Grade A, Grade C, and Grade D. Each grade has specific requirements regarding mechanical properties and chemical composition.

Key Features

  • High Strength: Designed to withstand high pressure and temperature.
  • Weldability: Excellent weldability due to the carbon-manganese composition.
  • Corrosion Resistance: Suitable for use in environments where corrosion is a concern.
  • Versatility: Applicable in various industries, including power generation and manufacturing.

Chemical Composition

Element Grade A (%) Grade C (%) Grade D (%)
Carbon (C) 0.06 - 0.18 0.06 - 0.18 0.06 - 0.18
Manganese (Mn) 0.30 - 0.90 0.30 - 0.90 0.30 - 0.90
Phosphorus (P) ≤ 0.035 ≤ 0.035 ≤ 0.035
Sulfur (S) ≤ 0.025 ≤ 0.025 ≤ 0.025
Silicon (Si) ≤ 0.40 ≤ 0.40 ≤ 0.40

Mechanical Properties

Property Grade A Grade C Grade D
Yield Strength (ksi) 30 min 35 min 40 min
Tensile Strength (ksi) 48 min 50 min 55 min
Elongation (%) 30 min 25 min 20 min
Hardness (Rockwell B) 80 max 80 max 80 max

Steel Grade

  • Grade A: Suitable for low-pressure applications.
  • Grade C: Designed for moderate pressure applications.
  • Grade D: Intended for high-pressure applications.

Application

ASTM A178 welded steel tubes are primarily used in:

  • Boiler components
  • Superheaters
  • Heat exchangers
  • Other high-temperature applications in power plants and industrial processes.

Possible Alternative Grades

  • ASTM A53: A general-purpose steel pipe with similar applications.
  • ASTM A106: Seamless carbon steel pipe for high-temperature service.
  • ASTM A192: Seamless carbon steel boiler tubes for high-pressure applications.
